Filter press

Filter presses provide physical liquid-solid separation in a wide variety of industrial processes.

The suspension to be filtered is transferred by an infeed pump into the filter chambers where it presses against the liquid-permeable filter medium. Solids retained on the filter medium accumulate, forming the filter cake. As the filter cake grows, it provides the filtration action to an ever-greater extent, taking over from the filter medium.

The location of solids retention shifts during the filtration process. At first, solids are retained on the surface of the medium and later within the volume of the filter cake.

The position and direction of the suspension infeed can be configured in accordance with users’ requirements. In certain cases, process considerations call for decentralized or corner infeed as opposed to the more commonly used central infeed configuration.

Filtrate take-off can be realized by conventional open or closed outlet systems and/or drip-tight plate designs.

In conventional chamber filter presses, the infeed pump transfers the suspension during the entire filtration cycle. At the start of the cycle, the volume flow rate is high due to the low pressure drop across the filter medium. As the filter cake increases in thickness, the volume flow rate decreases due to increased pressure drop.

We have 2 sizes of filter press’ in our product program. A 30 L. and a 150 L. 

The outlet of the peristaltic pump is to be connected to the inlet of the filter press.

The water which is being cleaned from any sludge when passing through the filter press is running out on the back side of the filter press where it is collected in a trench from which the clean water is to either run into a buffer-tank and then being pumped directly over to a PE-tank for being re-used. Alternatively, a pump can be installed to lead the clean water coming out of the filter press directly into the PE-tank.

The filter press will be prepared with PP plates ensuring that a close environment for the water at all times as well as collecting the clean water in a trench designed to either fun into a buffer-tank or via a hose & a pump to be pumped to a water reservoir
